Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
As shown in Figs. 1-5, a kind of novel VOCs exhaust gas dry type pre-processing system equipment, including shell 1, setting are in shell
The forward spin flow separator 4 that 1 top of shell is arranged in, 1 lower part of shell is arranged in the centrifuge separation head 2 and liner 3 at 1 middle part of body
The support of lower cyclone separator 5, the soiling solution dust collecting box 6 that 1 bottom of shell is set and the lower end for being fixedly connected on shell 1
Leg 10.
The top of shell 1 opens up gas outlet 100, and gas outlet 100 is connected to escape pipe, and escape pipe connects blower, centrifuge separation
First 2 be the helical channel with air inlet 200, has filter wall on liner 3, liner 3 is arranged inside shell 1, centrifugation point
It is set in outside liner 3 from first 2.
Forward spin flow separator 4 is led including the first circular support 400, the first taper being arranged in the first circular support 400
Stream cap 401 and multiple rings are located at the first guide vane 402 between the first circular support 400 and the first conical flow guiding cap 401,
Multiple first guide vanes 402 constitute a circular conical surface, and the tapering of the first conical flow guiding cap 401 is downward.
Upper barrel 7, the lower end of the first guide vane 402 and upper cylinder are fixedly connected between liner 3 and the first circular support 400
